The concepts of quantum technology promise to achieve more powerful information processing than is possible with even the best possible classical computers. To actually build efficient quantum computers remains a significant challenge in practice. A new scheme termed "coherent photon conversion", could potentially overcome all of the currently unresolved problems for optical implementations of quantum computing. The international team of scientists led by researchers from the Vienna Center for Quantum Science and Technology (VCQ) at the University of Vienna (group of Anton Zeilinger?) introduces this new scheme this week in Nature.
